The Imo Incident, also sometimes known as the Imo Mutiny, Soldier's riot or Jingo-gunran in Japanese, was a violent uprising and riot in Seoul beginning in 1882, by soldiers of the Joseon Army who were later joined by disaffected members of the wider Korean population. The revolt broke out in part due to King Gojong's support for reform and modernization, as well as the employment of Japanese military advisors. Some sources credit rumors as the spark which ignited violence, where many Korean soldiers were worried by the prospect of incorporating Japanese officers in a new army structure. The trigger for the riot is largely attributed to a reaction about unpaid soldiers wages, who found sand and bad rice in soldiers' rations. At the time, soldiers could be paid in rice as it was used in place of currency.
The rioters killed many government officials, destroyed homes of high government ministers and occupied the Changdeokgung. They also turned on the members of the Japanese legation in the city, who barely escaped aboard the British ship HMS Flying Fish. During the day of rioting, a number of Japanese were murdered, including military advisor Horimoto Reizo. The rioters also attacked the home of Min Gyeom-ho, who held joint appointments of Minister of Military Affairs and high-level official of the Agency to Bestow Blessings, lynched lord Heungin, Yi Choe-eung and attempted to murder Queen Min, even reaching the Royal Palace. The poverty-stricken people of Seoul from Wangsim-li and Itaewon joined in the riot and Queen Min escaped to the home of Min Eung-sik by disguising herself as a lady of the court.
